The presence of snow on the ground and freezing temperatures probably have pushed anything to do with your home's air conditioner system way out of your focus. However, don't forget to care for your unit this winter season. How well you care for and protect your unit during the off season will have a significant effect on how well it performs once the warming temperatures come back around.
If you live in an area with harsh weathers, it's a good idea to cover the outdoor unit. Heavy snow or ice precipitation provide a perfect inlet for moisture to get inside the system. High moisture levels combined with freezing temperatures can lead to damage. When choosing your cover, choose wisely.
First, make sure it's actually waterproof. Secondly, make sure it fits snugly at the base of the unit. If it does not, critters can get inside the cover and make your A/C unit their home for the winter. If they get inside and start chewing on the wires, they can cause extensive damage.
Make a commitment to perform seasonal cleanup. If all the leaves have fallen from the trees near your A/C unit, make sure you are clearing them away. First, leaves hold moisture. If you live in a climate with mild temperatures, the moisture from the leaves can cause mold to form inside the unit. In colder climates, the moisture from the leaves can freeze and cause damage as well.
However, leave accumulation inside the unit can cause costly damage to the heat exchanger. In terms of winter precipitation, even if you do have a cover, don't let excessive amounts of ice or snow buildup on the cover. The weight of this accumulation puts undue stress on the system and can cause damage.
As winter starts to draw to a close, consider having an inspection performed by an HVAC professional. Although you won't likely need to turn on your unit right away, having the inspection performed this early gives you ample time to address any problems and have the repairs performed.
Additionally, if you wait until the temperatures rise enough to actually need air conditioner, many of the technicians in your local area will likely be bombarded with service calls for winter damage. Performing the inspection early allows you to get ahead of the crowd and ensure your unit is ready for the warmer weather.
Taking the time to focus on your unit during the winter can help you keep your repair costs down and ensure your unit is ready for use when you need it. For more information, contact companies like Aggressive Mechanical Contractors.
